Actually his advertisement placement is quite good, but the advertisements at the left side should really get removed.. the overall color and "texture" or feel to it is good though, and good loading time. Good site overall, good luck!
You can change the theme as there are loads of free themes available. As far ads goes, they are nicely placed. Over all a good blog.
Based on my observation, ad placements are quite good. But I suggest you also include ads in your content And a premium wordpress theme would be better, IMHO!
Thanks anyone review my blog + I'm not change theme, because i like this theme + I'm using UK hosting, hope will load fast + I hope my seo tip will help webmaster make good site (pagerank, traffic, backlink, seo) Cheer
